Complete C
NOTES:
1. Compressor and blower motor thermally protected internally.
2. All wiring to the unit must comply with NEC and local codes.
3. Transformer is wired to 460 v (BLK/RED) lead for 460/3/60
units. Transformer is energy limiting or may have circuit
breaker.
4. FP1 thermistor provides freeze protection for water. When
using antifreeze solutions, cut JW3 jumper.
5. Typical thermostat wiring shown. Refer to thermostat installa-
tion instructions for wiring to the unit. Thermostat wiring must
be Class 1 and voltage rating equal to or greater than unit sup-
ply voltage.
6. Factory cut JW1 jumper. Dry contact will be available between
AL1 and AL2.
7. Transformer secondary ground via Complete C board stand-
offs and screws to control box. (Ground available from top two
standoffs as shown.)

8. Fan motors factory wired for medium speed. For high and low
speed remove BLU wire from fan motor speed tap ‘M’ and con-
nect to ‘H’ for high or ‘L’ for low.
9. For low speed remove black wire from BR6 and replace with
red. Connect black and brown wire together.
10. Optional LON wires. Only connect if LON connection is desired
at the wall sensor.
11. For blower motors with leads, for medium or low speed, discon-
nect black wire from BR6. Connect black and orange/purple
wire together. Connect red for low or blue for medium to BR6.
12. Fan motors factory wired for medium speed. For high and low
speed remove BLU wire from fan motor speed tap ‘M’ and con-
nect to ‘H’ for high or ‘L’ for low. Remove brown jumper wire
from tap. Insulate open end of brown jumper.
